REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 427 
convex above ; the normal grooves and furrows are not very strongly marked, except the 
- indentation on the hind slope, which is broad and deep; the centre of the caput is slightly 
gibbous and rounded, sloping a little both fore and aft; clypeus low, its height not ex- 
ceeding the diameter of one of the fore central eyes. Colour pale dull yellow ; margins 
black, and a blackish angular or arrow-head marking with its point directed backwards 
at the occiput, showing the junction of the caput and thorax. 
Eyes on slightly tubercular black spots, in four pairs, and not greatly differing from 
each other in size ; those of the front central pair are the smallest and darkest of the eight, 
and are near together, but not touching; those of each lateral pair are placed obliquely 
and touch each other; the space between the hind centrals is equal to that between each 
of them and the lateral one on its side of the front row ; each of the hind centrals, in 
fact, forms with the two of the front row nearest to it an equilateral triangle. 
-Legs long, rather slender; relative length 4, 1, 2, 3, furnished sparingly with hairs, 
and afew fine spines on their uppersides. Colour pale yellow ; palpi short, similar to the 
legs in colour, except the digital joint, which has a brown tinge, and the palpal organs, 
which are red-brown. The cubital and radial joints are both short and about equal in 
length; the former has on its upperside forward a single long, strong, curved, promi- 
nent tapering bristle; the radial has a few inconspicuous hairs on its upperside, and 
spreads out slightly at its extremity, principally on the inner side. Digital joint large, of 
a somewhat irregular form, broader before than behind, being produced into a sort of 
lobe on either side forward, and with a small conical protuberance at its base on the 
upperside near the radial joint; palpal organs well developed, prominent, complicated, 
consisting of various lobes and corneous spiny projections. 
Falces moderately long, not very powerful, vertical, divergent, armed with several longish 
teeth on the inner side at the extremity ; similar in colour to the cephalothorax. 
Maxille strong, not very long, slightly inclined towards the labium; the outer margin 
rounds gradually from near the base to the inner extremity. 
Labium short, semicircular, and, with the maxillæ, of the same colour as the falces. 
Sternum broad, heart-shaped, furnished with hairs, similar in colour to the labium dc. 
_ Abdomen narrow, oval, moderately convex above, furnished sparingly with short hairs ; 
it is of a dull whitish yellow, mottled on the upperside with white cretaceous-looking 
spots, or small blotches, principally in the median line, where they form a sort of 
pattern. Near the fore margin is a conspicuous subtriangular black patch pointing for- 
ward, its sides, which are longer than its base, are hollow ; there are faint traces on the 
hind portion and on the sides of other black lines and spots, but no pattern discernible ; 
perhaps other specimens would show some variety in this respect. This species, of which 
only a single specimen has come under my notice, was forwarded to me by the late 
Mr. Richard Beck, of Cornhill, London, among many other interesting spiders captured 
in the neighbourhood of London, and appears to me to be undescribed. It is allied to 
L. longidens, but easily distinguished by having the specific characters which denote 
that species much less strongly marked; it is also much smaller in size.
